Practical Attribute-Based Multi-Keyword Search Scheme in Mobile Crowdsourcing

IEEE Internet of Things Journal, 2018
Cloud-based mobile crowdsourcing has been an attractive solution to provide data storage and share services for resource-limited mobile devices in a privacy-preserving manner, but how to enable mobile users to issue search queries and achieve fine ...

Ciphertext-Policy Attribute-Based Encryption with Multi-Keyword Search over Medical Cloud Data

International Conference on Trust, Security and Privacy in Computing and Communications, 2020
Over the years, public health has faced a large number of challenges like COVID-19. Medical cloud computing is a promising method since it can make healthcare costs lower. The computation of health data is outsourced to the cloud server. If the encrypted

Oblivious Multi-Keyword Search for Secure Cloud Storage Service

2017 IEEE International Conference on Web Services (ICWS), 2017
Outsource encrypted data has attracted attentions from industry and academics for storing sensitive data in third party clouds. Many cloud applications need privacy preserving multiple keywords search services over encrypted data with dual capabilities. On one hand, they need to keep the query keywords and associated search operations private such that

Fast Multi-keywords Search over Encrypted Cloud Data

2016
Searchable encryption (SE) allows a client to store his data in the Cloud in a way that it is encrypted but still searchable by the server. However, when doing multi-keywords search (MKS), most SE schemes seems to be rather inefficient. In this paper, we design and implement an SE scheme that allows the MKS indices to be pre-built secretly at the ...

Enabling Fine-Grained Multi-Keyword Search Supporting Classified Sub-Dictionaries over Encrypted Cloud Data

IEEE Transactions on Dependable and Secure Computing, 2016
Using cloud computing, individuals can store their data on remote servers and allow data access to public users through the cloud servers. As the outsourced data are likely to contain sensitive privacy information, they are typically encrypted before ...

Algorithm for Multi Keyword Search Over Encrypted Data in Cloud Environment

International Conference on Wireless Communications and Mobile Computing, 2020
Cloud Computing offers storage resources as well as network and computing resources to the organizations. This eliminates the high infrastructure cost for the organizations that are using these services as they can now dynamically pay for these services,

Generic Multi-keyword Ranked Search on Encrypted Cloud Data

2019
Although searchable encryption schemes allow secure search over the encrypted data, they mostly support conventional Boolean keyword search, without capturing any relevance of the search results. This leads to a large amount of post-processing overhead to find the most matching documents and causes an unnecessary communication cost between the servers ...

Dynamic Policy Attribute Based Encryption and its Application in Generic Construction of Multi-Keyword Search

Int. J. E Serv. Mob. Appl., 2019
Attribute based encryption (ABE) is an encryption technique which provides a good solution to the security issues in the cloud environment. Through ABE, a data owner can achieve the fine-grained sharing of data encrypted under attributes or an access ...

Secure multi-keyword search supporting dynamic update and ranked retrieval

China Communications, 2016
As cloud computing is becoming prevalent, data owners are motivated to delegate complex data managements to the commercial cloud for economic savings. Sensitive data is usually encrypted before being uploaded to the cloud, which unfortunately makes the frequently-used search function a challenging problem.
